UNITED STATES PATENT @F1-Ica IMPROVEMENT IN PENCIL-CASES.

Specification forming part of Letters Patent No. 165,009,

dated June 29, 1875 application lild December 3, 1874.

To all whom it may concern Be it known that I, WASHINGTON I. LUD- LOW, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Pencils, of which the followingfis a specification:

The nature of my invention relates to a pencil, whether the same be of lead, slate, or otherwise; and it consists in a hollow cylinder or holder, in either end of which the pencil may be inserted. This cylinder maybe of metal. hard rubber, or other 4suitable material, and itis provided with an internal screw-thread. The aperture left at the top is suitably iilled which adds to the symmetry and linished appearance of the complete pencil. v.

In the accompanying drawing, the several figures illustrate my improved pencil, constructed, according to my invention, in longitudinal section and side elevation. In the saiddrawing, A represents the hollow cylinder or case, which is made of sui table shape and material, and is provided with a screw-thread, a. This screw may extend thc entire length of the case, if desired. B represents the pencil, of convenient shape and material, and it may be provided with a slight screw-thread on its outer surface, or, when made of a soft material, as cedar wood, the screw will be formed by the thread in the cylinder or case, when the pencil is inserted and turned to project from the holder. (l represents an ornamental cap, which is inserted in the hole at the top of the case. p

A modification of my invention is shownin Fig 5 of the drawing. In `this modification the case is also made of wood, or hard rubber, or other suitable material. A small cylinder, of three-eighths of an inch,

more or less,ofmetal`,and provided both on its outside and insid'esurfaceswith a screw-thread.,

is inserted in the cylinder or case at the point thereof. It may be held in place by means of the screw-thread on. itsouter surface, ormsecured by glue, or in'any other desirable manner. TheV pencil is inserted at the other extremity of the case and'passes'tlrough this small'cylinder. l

The operation and advantages of my invention areobvious. The pencil is introduced at the top of the "case, and, if not previously provided with a screw-thread corresponding to the female screw of the case, it receives one asidiseforcedthrough. The aperture left isztlled with the cap O. As fast as the pencil is used up it is forced forward by simply turnipgpitjntthe case.V

I do away with short pencils, `as I preserve the fiill length of the holder or nc ase. The pencil may be used up almost entire.

It is economical in consequeiice of the lessened cost to the-consumer.

I do away with the necessity of finishing the outside of the pencil, which adds nearly one-half to the cost of an ordinary pencil.

What I claim isl. The hollow cylinder or casing A, having an aperture at'each end and an internal screwthread, in combination with ,the pencil Il, adapted to move through said hollow cylinder or casing, substantially as and for the purpose described.

2. The hollow case A, provided with screwand the ornamental cap O, in combination With-the pencil B, substantially as shown and specified.

In testimony that I claim the foregoing, I have hereunto set my hand.

WASHINGTON I. LuDLoW.
